The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest ...

If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

Researchers at the Hebrew University of Jerusalem have overturned a 180-year-old scientific assumption, proving ...

In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed ...

A tiny device that entangles light and electrons without super-cooling could revolutionize quantum tech in cryptography, ...

"These single atoms are like the smallest slits you could possibly build." For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the ...

Since then, countless experiments have confirmed that light always travels at the same speed in a vacuum — about 300,000 ...

Researchers in Konstanz discovered a way to manipulate materials with light by exciting magnon pairs, reshaping their magnetic “fingerprint.” This allows non-thermal control of magnetic states and ...

The research team has observed Floquet effects in graphene, paving the way for innovative new technologies. Graphene is a remarkable "miracle" material, consisting of a single, atom-thin layer of ...
